# Package MPI

Python interface to the Message Passing Interface (MPI)

This module contains a Python interface to the Message Passing Interface (MPI), and standardized library for message-passing parallel computing. Please read an introduction to MPI before using this module; some terms in the documentation do not make much sense unless you understand the principles of MPI.

This module contains an object, 'world', which represents the default communicator in MPI. This communicator can be used directly for sending and receiving data, or other communicators can be derived from it.

A number of global constants are also defined (max, min, prod, sum, land, lor, lxor, band, bor, bxor, maxloc), and minloc). They are used to specify the desired operator in calls to the 'reduce' and 'allreduce' methods of the communicator objects.
